Your vehicle’s oxygen sensor is part of an emissions control system. The overall purpose of the sensor is to ensure your automobile’s engine runs as efficiently as possible. Your vehicle’s computer uses its input to regulate the fuel mixture, which is referred to as the fuel "feedback control loop." The computer takes its cues from the sensor and responds by modifying the fuel mixture to achieve the optimum air-to-fuel ratio level. When this car part has failed, your vehicles on-board computer will no longer be able to accurately detect the engine’s air-to-fuel ratio. If this happens, your vehicle will perform poorly and use more fuel than necessary.
